Privacy & data handling

Tentaco runs this tool in your browser whenever possible. Files you select are processed in memory on your device and are not uploaded to Tentaco servers for standard modes. Close the tab or clear the page after use on shared computers. Features that call external APIs (such as URL fetchers) only send the data required for that request.
